An inquiry is used to record any general queries a customer may have about goods or services they
are thinking of buying from your company. An inquiry is one of the first possible documents you can
create in the customer order management cycle. An example of the type of information contained in an inquiry is whether your company stocks a certain product line. Along with entering general customer queries, you can use inquiries to record the goods or services that a customer is interested in. And you can enter descriptions of goods or services that your company should research in order to answer customer queries. You can carry out automatic pricing for any goods or services you enter in an inquiry. This will enter the price of goods or services into the inquiry for you. You can also check whether any goods you entered in the inquiry are available in your company's warehouse. The order probability function enables you to determine the likelihood that a customer will buy from you. To increase the probability of a sale, you can offer the customer alternative goods and services.

Quotations are sales query documents that you create when a customer requests specific information
about a product. For example, you can use a quotation if a customer makes a query regarding how much goods or services cost or you can use a query if a customer asks when goods will be available for shipping.
You can create quotations from scratch or you can create them by copying inquiries. If a customer is
interested in the products or services after they have made an inquiry, you can provide a quotation based on the original inquiry. R/3 allows you to copy the information directly from an inquiry to a quotation.
Let's say an inquiry was created when a customer inquired whether your company, could manufacture
twenty motorcycles. Assume a quotation was created by copying this inquiry when the customer called
back to inquire how much twenty motorcycles would cost. You can use quotations to enter information and descriptions for goods and services that are to be researched. You can also use them to carry out automatic pricing and to check goods availability. You can use quotations to calculate the probability that a customer will buy the goods or services entered on a quotation. This function is called order probability. You can also use quotations to enter details about alternative goods or services. These are goods or services that a customer did not inquire about but that you think they will consider purchasing. Once you have created a quotation for a query in R/3, you send the quotation to the customer who made the query. The quotation represents a binding offer made to the customer that includes quantity and cost details.
You create a free of charge delivery when you send free samples of any goods that your company
produces to customers. These contain information about the goods that are delivered but they don't
include the corresponding pricing information for them.
Let's look at the sales orders that exist in R/3.You create a sales order when a customer has ordered
goods or services from your company. They are a part of the customer order management cycle.
You can carry out automatic pricing in sales orders to enter the price of goods or services.
R/3 will also run a credit check on the customer to see if they will be exceeding their credit limit.
You can also check whether ordered goods will be available in your company's warehouse for delivery.
Examples of types of sales order include
• standard orders
• consignment orders
• cash orders
• rush orders
You create standard orders for goods and services that will be delivered or rendered according to
the standard R/3 sales cycle. This means that goods are ordered, picked from the warehouse, and
then shipped before customers are billed for them. Likewise, services are rendered before customers
are billed for them.
Your company may store its goods in its customers' warehouses. You create a consignment order when a customer is ready to retrieve stock from the warehouse.
SAP can propose the most suitable stock to retrieve, including third-party stock.
A consigment order is like a standard sales order for goods but it doesn't have any delivery
information.
You create cash orders and rush orders for the sale of goods only.
You create a cash order when a customer picks up and pays for a delivery as soon
as it is ordered. And you create a rush order when the customer picks up the goods on the
same day as the order is placed. In this case, the invoice is created later.
You can arrange to deliver goods or render services in installments. To do this, you create an
outline agreement. Examples of some types of outline agreement include :
• quantity and value contracts
• master contracts
• scheduling agreements
• service contracts
You create a quantity contract if a customer has agreed to order a certain quantity of goods from your company during a specified period.
And you create a value contract if a customer has agreed to order goods of a certain cumulative value from your company during a specified period.
Quantity and value contracts do not include delivery dates, so releases are made using a sales order.
You can unite multiple contracts in a single master contract.
Let's say you create a quantity contract because a customer has agreed to order 500 engines in the first six months of the current year. If the customer orders 100 of these engines in January, you create a sales order called a release order.You refer to a quantity contract in a release order. So you refer to the quantity contract created for the 500 engines in each release order created for these engines. R/3 will then update the quantity contract automatically so it contains the correct number of remaining engines to be ordered.
Scheduling agreements specify the installments in which goods will be delivered to a customer. They include the quantity of a product that will be delivered in each installment. And they include the delivery date of each installment. You process a delivery for each installment contained in the scheduling agreement in the same way that you process a delivery for a regular sales order.No sales documents, such as release orders, are created before the products included on a scheduling agreement are processed for delivery.
You create a service contract if a customer requests a service over a particular period of time. For example, you could create a service contract if a customer ordered five one-hour maintenance checks from your company's motorcycle repair department.
You create complaint sales documents if there has been a fault with any goods that have been delivered, or with any services rendered, by your company.
For example, you create complaint sales documents if customers have been billed
incorrectly for an item or service, or if goods are faulty.
Different types of complaint sales document include
• returns
• credit memo requests
• debit memo requests
You create a returns document if a customer returns goods they have purchased from you because they are not satisfied with them. You can create returns from scratch or you can create them by copying the sales order that was originally created for the returned delivery.
A returns document records that you expect stock to be returned to your warehouse.
You can create one or more credit memo requests if a customer has been overcharged for a quantity of goods or services. You can also create a credit memo request if goods were damaged during transit and you want to credit the customer for the goods damaged.
When you create a credit memo request, your Accounting department reviews it to confirm that it can be justified. If the credit memo request is approved, the Accounting department creates a credit memo based on the request. You can create credit memo requests by copying other sales documents such as the sales order where the overcharge occurred.
You create debit memo requests when customers have been undercharged for products or services. Your company’s Accounting department can then create an invoice to bill the undercharged customer.

Process Flow
The typical procurement cycle for a service or material consists of the following phases:1. Determination of Requirements
Materials requirements are identified either in the user departments or via materials planning and control. (This can cover both MRP proper and the demand-based approach to inventory control. The regular checking of stock levels of materials defined by master records, use of the order-point method, and forecasting on the basis of past usage are important aspects of the latter.) You can enter purchase requisitions yourself, or they can be generated automatically by the materials planning and control system.2. Source Determination
The Purchasing component helps you identify potential sources of supply based on past orders and existing longer-term purchase agreements. This speeds the process of creating requests for quotation (RFQs), which can be sent to vendors electronically via SAP EDI, if desired.3. Vendor Selection and Comparison of Quotations
The system is capable of simulating pricing scenarios, allowing you to compare a number of different quotations. Rejection letters can be sent automatically.4. Purchase Order Processing
The Purchasing system adopts information from the requisition and the quotation to help you create a purchase order. As with purchase requisitions, you can generate Pos yourself or have the system generate them automatically. Vendor scheduling agreements and contracts (in the SAP System, types of longer-term purchase agreement) are also supported.5. Purchase Order Follow-Up
The system checks the reminder periods you have specified and - if necessary - automatically prints reminders or expediters at the predefined intervals. It also provides you with an up-to-date status of all purchase requisitions, quotations, and purchase orders.6. Goods Receiving and Inventory Management
Goods Receiving personnel can confirm the receipt of goods simply by entering the Po number. By specifying permissible tolerances, buyers can limit over- and under deliveries of ordered goods.7. Invoice Verification
The system supports the checking and matching of invoices. The accounts payable clerk is notified of quantity and price variances because the system has access to PO and goods receipt data. This speeds the process of auditing and clearing invoices for payment.

Pur info record is nothing but a master data like thing which will be maintained for different materials to determine the prices etc.It Specifies the number that uniquely identifies a record.
For Example: an info record is based on Plant Vendor and Material Based on these three the Material Prices will be calculated for different combinations different values are taken into consideration.
During pricing it brings these values automatically based on this info record.
Use ME11 Tcode to create this record.
